Coli bacteria, and in DNA hybridization studies. A current trend in these biosensing systems is to move away from clinical laboratories where expensive bulky equipment and highly skilled personnel are needed and move to point-of-care-testing (POCT). Monitoring a physiological signal such as blood glucose levels in a patient with a wireless sensor provides a good example. A major challenge to the incorporation of wireless sensors for biosensing/medical applications is power consumption. Inspired by the concept of phononic crystals (PCs), we incorporate microcavities in the form of periodic inclusions in a SAW devices made of 90 ° ST-X Quartz and 36° YX LiTaO3. We utilize a three-dimensional (3-D) finite element model (FEM) to compare insertion loss (IL) and mass sensitivity of SAW sensors having microcavities and show that significant improvements in sensitivity and power consumption can be obtained. The resulting metamaterial has properties different than those of the host material; in particular, density and elastic properties. To harness the potential of PCs within a SAW sensing device, we have systematically evaluated properties such as size, periodicity and nature of the filling materials because these affect the center frequency, power consumption, width of the bandgap, and sensor sensitivity among other things. Our simulation and experimental results suggest the possibility of tuning the acoustic band-gap and acoustic confinement to realize novel SAW and SH-SAW phononic sensors having low insertion loss and high sensitivity.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"42 1","pages":"213-216"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87490639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The platform is comprised of a five stage Dickson voltage multiplier, a dynamic impedance matching network (DyIMN), an XLP microcontroller (MCU) and an RFID tag IC with an embedded temperature sensor. Device range operations have been assessed up to a distance of 1.5 m from the RF source, corresponding to a minimum RF input power of -10 dBm. Firmware optimization leads to a reduction of power dissipation below 500nW in sleep mode, allowing an optimal energy harvesting and storage from the RF source. The harvested power enable logical operations to be completed from MCU, thus enabling sensing and storing of temperature measurements directly into the user memory of an RFID tag. Also the efficiency of the energy harvester is calculated from the MCU, hence tuning the DyIMN dynamically to respond over a wide range of input power and load impedance. The experiments demonstrate the feasibility of the system to operate autonomously within the reading range of a standard RFID reader, that acts both as RF power source and receiver of the data stored in the tag user memory.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"5 1","pages":"1208-1211"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80123599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The platform integrates several working electrodes (WE), pseudoreferences (pRE) and a counter electrode (CE) for electrochemical detection. The bio-lab-on-a-chip allows the detection of changes in real time, with rapid response, allowing to measure small volumes and fast cell metabolisms changes. The reliable analytical performance of the platform in in-vitro conditions has been demonstrated.
